# Video Models

Video models cover text-to-video, image-to-video, reference-guided generation, editing, avatars, and post-processing. Check each model for supported resolutions, durations, and control inputs (first/last frame, reference video, etc.).

## Technical topics

* **Text-to-video (T2V)**, Generate clips from natural language prompts.
* **Image-to-video (I2V)**, Animate a still image with motion and optional audio.
* **Frame & reference control**, First/last frame, keyframes, or reference video for consistency.
* **Editing & VFX**, Erasing, background removal, resolution upscaling, retakes, lip-sync.
* **Avatars & characters**, Talking-head and identity-aware pipelines where offered.
* **Duration & aspect**, Max length, FPS, and aspect ratios are model-specific; see per-model docs.

## Model API & platform docs
